The son of a mining engineer, Ericsson showed an early interest in mechanics. By the age of ten, he had designed and constructed a miniature sawmill and by 13, he was a cadet in the Swedish navy. By the age of 17, he entered the Swedish army, joining as an ensign in the 23rd. Corps, a specialized engineering unit for the army. While serving in the army, Ericsson became interested in steam engines and developed the theory for his caloric engine, which operated on the principle that air heated to very high temperature could be used to drive engines. In 1826 Ericsson published a paper on his work to develop a caloric engine. That year he demonstrated his invention to the British Society of Civil Engineers. Although the engine failed in the demonstration, Ericsson impressed the English engineer John Braithwaite. Braithwaite was impressed with the young Swede's determination and offered him a position as a partner in his firm.
